Read a line after reading int for <no_people>.
Scanner.nextInt() leaves a '\n' in the input stream buffer which failed the Scanner.nextLine() call for reading <status>.
Calling in.nextLine() after the call to Scanner.nextInt() consumes the leftover '\n', allowing successive Scanner.nextLine() call to read <status> correctly.
int no_people = in.nextInt();
in.nextLine ();
// read <status> here
